Alright this is a reach but worth a shot. First time posting on a thread like this. I’m a mechanical engineering student that is working with a sponsor who wants us to build an automated fly fishing system for someone who is paralyzed from the waist (correction: neck down). The biggest concern is how to achieve the linear motion necessary, yes we have simplified this art form to only 2 degrees of freedom. This linear system needs to have a speed of about 11 in/s, carry about 10 lbs, and be able to hold a linear force of about 15 lbs. we have found that ball screws can hold the weight but can’t achieve the speeds and a belt drive can do the speed but can’t hold much weight without skipping. Does anyone know of a linear rail belt driven system configuration that can achieve this? The idea now is to use a nema stepper and a belt and pinion system. How could I keep the belt from skipping at high speeds and and have the gantry wheels hold this weight? This is the first time we have designed a linear system like this. Any help and suggestions would be greatly appreciated.
